To LN '10ft/m2, it 712.04/ cri/werft.-

Be it known that I, CELEsTTN PAUL MAIL- LARD, of Fisines, in theRepublic of France, have invented a new and useful Device forAutomatically Breaking Doubled Yarn in Spinning Mules and Jacks, ofwhich the following is a speciiication.

ln any mechanical process of spinni ng thread or yarn, the threads beingspun frequently break, and thebrolren ends become entangled with andtwisted upon adjacent sound threads, forming what is called doubledthreads,H thus damaging both threads. To remedy this it is usual tobreak the double threads and reunite them properly while the machine isrunning.

My invention embraces certain improvements adapted to self-actingspinning-mules, to break all the doubled threads at each drawing; and itconsists in the construction and combination of parts hereinafterdescribed and claimed, reference being had to the accompanying drawings,in which- Figure l represents one blade of one style of mythread-breakers. Fig. 2 represents a modification of my breakers, inwhich each blade is attached to an independent arm, and all these armsare secured to one rock-shaft.- Fig. 3 shows a series of blades unitedby one common back strip, to which they are all at` tached. Fig. i showsa series of blades in one continuons sheet of metal, it also showssomething of the manner ot' their action on thethreads. Figs. and 6 arerespectively side and top views of an arm for supporting blades. Fig. 7is a sectional elevation of part of a spinning-mule, showing my breakingdevice attached thereto, certain details being shown both in plan and inelevation. Fig. 8 is an elevation of my thread-breaking blades made asone continuous piece, the supporting-arms, rock-shaft, and means forrocking it.

A represents a portion of the stationary frame of a thread or yarnspinning-mule having the usual carriage,. B, carrying spindles b andi'aller C.

et represents the drawing-rolls, journaled inmain frame A, and adaptedto rock about a half acircle. Upon this shalt two or more arms, G, aresecured, carrying at their outer ends my breaking-blades. These bladesmay be one continuous sheet of metal, as shown at F, Fig. 8, or they maybe sections containing several blades in one piece, as in Fig. 4, or butone blade in a piece, as shown in Figs. 1 and 3. In the latter ease eachblade may be supported on an independentarni G, as in Fig. 2, or anumber of blades may be secured by their shanlrs upon a uniting-strip,f, Fig. 3, and then be secured upon arms G, like the one piece shown inFig. S. In all these styles each blade is lancet-pointed, and has ineach edge a loop-shaped opening, smallest at the edges of the blade,whereby each blade is provided with hooks at each edge, facing to thepoint and to the rear, and further provided with notches at y', Figs. 3and 4, or spaces, as in Fig. 2, corresponding to such notches. Theseblades are mounted on the rock-shaft E, in spaces centrally between thenormal positions ofthe threads being spun, and atevery advance of thespindle-carriage this shaft E is rocked, to thrust the blades up betweenthe threads, and at a given point the blades are allowed to swing downby their own weight. Then the threads all remain separate, they will bekept in line D, Fig. 3, so as to fall between the blades into spaces ornotches g', when the blades rise, and to rise therefrom without beingcaught by the hooking-edges of the blades when they fall but when onethread becomes attached to another this latter will be drawn out of lineby the first and assume a position to one side, as at D or D2, Fig. 3,and when the blades rise these threads will slide down the lancet endsthereof and spring under the hooks d, or as the shoulders y of theblades come in contact with said threads the threads will be crowdedunder the hooks d, as at e, Fi 4, and as the spinning continues the twostrands ot' the doubled thread will have been united and iixedrelatively to their present tensions, so that the united portion remainsin nearly the same vertical plane until the blades fall, when the hooksd/oi' the falling blades will engage said united portion of the doubledthreads and break them. This breaking is caused by the downward actionoi' the hooks on the threads, which also tends to carry the broken endsdown out ol' the plane of the whole threads, to prevent a secondentanglement, and to further prevent asecond entanglement the breakingis timed to take place While the faliers still remain elevated. Thus thebroken ends will be directed by the i'allers C to be Wound upon the endsof the spindles rather than upon the cop. This is a point of especialimportance, for when the broken ends wind upon the cop it takes time forthe attendant to search for the end, when a few seconds are of greatimportance, and the form ot' the cop is also liable to be injured bysuch search, thus damaging it for subsequent use. Therefore I time thefalling ot' :my breakingblades to the latest practicable instant, whenthere will yet be enough revolutions of the spindles to Wind up brokenthreads ou them before the fallers drop, and before the spinning anddrawing stop.

I l represent two pulleys journaled en the main frame A. Upon thesepulleys runs a rope, 7a., in a vertical plane parallel to the path ofthecarriage B. The tivo ends of this rope are secu red to the carriage bymeans of Winches M M. By loosening one ot1 the Winches and winding therope upon the other the rope may be set along either Way, as desired.This rope h moves With the carriage B as it travels to and fro inspinning.

H H .represent balls on or knots in the rope 7L for actuating thebreakers to rise by means of lever J. v

J is a forked t-\vo-armed lever secured upon the rook shaft E. In itsnormal position, (shown in Fig. 7,) this lever J is horizontal, with itsturned-np`bil`urcated end located eaeh side of the rope le, and thebreakingblades F hang down. lVhen the carriage moves out, the .rope Itis revolved in the directionY of the arrows. One of the stops H engageslever J and turns it over to the position shown in dotted lines, andelevates the breakingblades F with their arms G to nearly a verticalposi are engaged by the blade -hool s.

tion. So long as the stop H is over lever J the breaker will be heldelevated, and sueeeeding stops H to any required number Will so hold thelever and breaker until the proper time for the latter to fall, which isjust long enough betere the stretch of thread is completed to Wind thebroken threads upon the end of the spindles, as previously stated. XVhen the last stop H passes over the lever J the arms G, being no longerheld up, will drop by gravit-y, breaking vall the threads which Thestops H may be arranged to raise the breakers at any desired time and toallow them to fall after the passage of each stop, or at the point whichexperience in spinning any particular kind of yarn shows to be mostadvantageous.

R represents a spring secured to the frame of the machine to act on thehub of finger J, to steady its Vtall and to reeeive thelinger when itfalls to prevent shock, and to prevent the arms Gr from striking theframe.

l am aware that hooks for breaking doubled yarn on spinninginules havebefore been used, and l do not claim the same, broadly; but

lVhat l claim l. A series of laneet-pointed blades, F, each having thehooks d, inwardly-inelined shoulders g, and shaped or located to formthe notches or spaces g between them, as shown and described.

2. The combination, with the frame A, the carriage B, the rope Il., andthe stops H there ou, ot' the blades F, the arms G, the shaft E, theringer J, and the spring R, substantially as and for the purposespeciiied.

8. The combination, with the frame A, earriage B, rope 71, and the stopsH thereon, of the rock-shaft E, journaled in the stationary frame A, thearms G, secured on shaft E, and carrying breaking blades Orhooks F, andthe bifurcated arm J, as and for the purpose speciA tied. y f CELESTINPAUL MAILLARD. lVitnesses:
